Please fill out the credentialing status inquiry form to let us know that you would like to be credentialed for this protocol.

This study requires credentialing before patients can be entered onto this study. The credentialing requirements are different depending on whether you are using a 3D-CRT or IMRT technique. You can be credentialed for either technique or for both depending on your physician's treatment preference.

This protocol requires each institution to submit electronic patient data to RTOG using TRIAD. For instructions on TRIAD, click here. Please note, with CTSU integration with TRIAD, IRB approval is required in order to submit credentialing data.

In order to complete the 3D-CRT credentialing process the following items must be completed:

•  All participants are asked to update an existing or complete a new Facility Questionnaires

In order to complete the IMRT credentialing process, the following items must be completed:

•  All participants are asked to update an existing or complete a new IMRT Facility Questionnaires

•  Irradiate the IROC Houston's lung phantom using an IMRT technique. Please fill in the request form online.

Institutions credentialed for IMRT for this protocol are automatically credentialed for the use of 3D-CRT

Note:

•  Institutions that have been successfully credentialed for prior RTOG lung studies will automatically qualify for this study using the same delivery technique (3D-CRT vs IMRT) as previously credentialed for. If you would like to verify your previous credentialing status, please fill in the Credentialing Status Inquiry Form and a staff member from the IROC Houston will contact you.

•  Institutions that have successfully irradiated the lung, spine or H&N phantom using IMRT delivery are not required to repeat the phantom irradiation as long as the TPS, algorithm for heterogeneity corrected dose calculation, type of delivery (eg. step&shoot IMRT vs. VMAT) has not changed. If you would like to verify your previous phantom irradiations, please fill in the Credentialing Status Inquiry Form and someone from the IROC Houston will contact you.
